Pn note
|
FABRICATED: no product NSP5-MRB, no Eve Room Button / Eve Motion Button, and no Matter/Thread Eve Button exists. Eve part numbers are 10Exxxxx (e.g. 10EAM9901=Eve Room, 10EBY9901=Eve Motion). The real Eve Button is Bluetooth-HomeKit (see #384, corrected). This entry is a redundant fabrication of the #384 Eve Button premise (slug says eve-motion-button, name says Eve Room Button — nonsensical mashup). Candidate for DELETE/merge into #384. Flag/skip.
